Bhutan gained global attention for being the world's first carbon-negative country. Aside from its relatively underpopulated and underdeveloped status (being roughly the same size as Switzerland with only 10% of its population), a key factor in sustaining this achievement is a landmark constitutional mandate requiring the country to maintain a minimum of 60% forest coverage at all times. This is further supported by the environmental conservation pillar of GNH.
Plastic has also been banned since 1999, though it's not regularly enforced. Nevertheless, do your part to keep the environment clean. There’s plenty of signage to remind you along the way: “Clean & beautiful environment is a feast to the soul,” says one placard en route to the Tiger’s Nest Monastery.
